  1. kite:
    • definiton: no parellel sides one opp. angles = 2 sets of = sides
    • properties:
    • diagonals that are perpendicular 90 angles
    • 1 set opp. angles =
  2. isosceles trapezoid:
    • definition: one pare parellel sides legs are =
    • properties:
    • legs are =
    • diagonals =
    • bases angles are=
    • adj. angles = 180
  3. trapezoids:
    • definition: one pair of paralell sides and opp. sides are not =
    • midsegment -
    • connects the midpoints of the legs
    • formula M=1/2 (b1+b2)
  4. Square:
    • definition: 4 right angles and 4 = sides
    • properties:
    • all 90 angles
    • 4 = sides
    • opp. sides = and parallel
    • diagonals perpendicular
    • diagonals =
    • adj.angles = 180
    • 4 isosceles triangles
    • diagonals bisect opp. angles
  5. Rectangle:
    • definition: oposite sides that are = and paralle four 90 angles
    • properties:
    • adj.angles = 180
    • all 90 angles
    • diagonals are =
    • diagonals make 4 isosceles triangles
  6. Rhombus:
    • definition: parallelogram with 4 equal sides
    • properties of rhombi:
    • opp. angles are equal
    • adjacent angles equal 180
    • diagonals are perpinduculal
    • diagonals bisect opp. angles
  7. Parallelogram:
    deff.Opposite sides are parallel and equal

    • properties:
    • opposite angles are equal
    • adjcent angles add to 180
    • diagonals bisect
